In existing steam boiler plants there is the greaseand packing material is very substarr known disadvantage that, in conducting tial'. away the steam, liquid is entrained so that It is possible to install the apparatus in a wet or moist steam is used for driving the any boiler plant, since by the provision of power plant. The consequence of this is that hinges the water separatinggplatescan be 55 condensed water which is deposited in large passed through the manhole opening in a quantities sets up a counteraction and in collapsed condition.v starting and driving the engines damage may The subject of the invention is illustrated be done, such as fracturing the top of the by way of example in'the accompanying piston, unsealing the stuiling box glands, drawing wherein: I Fig. 1 is'a'longitudinal 60 pipe lines and so'forth. A large reduction section through the steam drying or water in steam pressure leads to a large coal conseparating device (steam trap) built into a sumption or oil consumption as well as a boiler." r i large amount of wear of the stufling box ma- Fig. 2 is a longitudinal section through terial and heavy strains on the materials in the steam dome ,with manhole and steam general. drying and waterseparation device fitted in; The essence of the present invention con Fig. 3 'is a plan of the water separating sists in that the steam produced in the boiler plates connected. in hinged form and to be is used as dry steam, this being effected withfitted into the manhole".

The two water separating plates 6, f, and is, Z, are eachprovided with two valve discs p under spring action which serve for the purpose ofallowing the steam'to pass without hindrance through the plate. valves 39 from the steam generating chamber at to the steam dome c in case of any choking up of the water passage slots 0 against the two rings m, m,'being produced by boiler scale etc. during the generation of steam. This construction of water separating plates produces the effeet that the steam which is saturated with water iscompelled to impinge on many points in order'thus to separate the water which it carries.

The steam eduction pipe, 9 provided on the dome 0 is adjoined inside thesteam dome c by a long sweep bend 7' which serves to take the tubular extension 8, the diameter of which varies and which is covered at the top by a hood t. The slots u arranged below the hood it serve as steam inlet apertures for the steam pipe 7', 9. The outer Wall of the tubular member 8 is provided with a number of water separating plates or fins '0 of different diameters. The steam drawn ofi through the steam pipe 9 strikes against the stepped arrangement of separating plates '0 and the steam to be dried rebounds several times against the separating plates '0, so that the choked.
